UK e-Infrastructure 7 The National Grid Service The core UK grid, resulting from the UK's e- Science programme. Production use of computational and data grid resources. Supported by JISC, and is run by the Grid Operations Support Centre (GOSC).

UK e-Infrastructure 16 How Do I Get A Certificate? You need a valid UK certificate before applying for an NGS account: –https://ca.grid-support.ac.uk, the UK Certificate Authority.https://ca.grid-support.ac.uk –You will probably need to provide non-electronic proof of identity to your local representative of the CA. For example: show your passport. See –Always keep this certificate secure. E.g. DO NOT LEAVE IT ON ANY NGS CORE NODE ! Do store it on a USB drive, that you keep safe!!

UK e-Infrastructure 17 Projects and VOs Just need access to compute and data resources for users in your project? –Currently, mainly applications from individuals –project-based applications being dealt with case-by-case, as procedures are established – for these, talk to GOSC! Want to host your data on NGS? –consider SRB, Oracle, or OGSA-DAI –NGS maintains infrastructure –you populate and manage data Want to use NGS resources to provision services, portals for a community of users? Want researchers to access your data?

UK e-Infrastructure 24 Enhancing useability - 1 NGS has deployed low-level tools: these are reliable and give a production service but a user interacts at a low level with resources. GOSC had no adequate alternatives. Need for higher abstractions & tools is evident Example: P-GRADE and GEMLCA, developed at SZTAKI, Hungary and University of Westminster are made available to NGS users – –www.lpds.sztaki.hu/pgportalwww.lpds.sztaki.hu/pgportal –www.cpc.wmin.ac.uk/ngsportalwww.cpc.wmin.ac.uk/ngsportal

28 What is a P-GRADE Portal workflow? a directed acyclic graph (DAG) where –Nodes represent jobs (executable batch programs) –Ports represent input/output files the jobs expect/ produce –Arcs represent file transfer between the jobs semantics of the workflow: –A job can be executed if all of its input files are available local input files: on the portal server remote input files: at Grid storage service providers

31 GEMLCA objectives To deploy legacy code applications as Grid services without reengineering the original code and minimal user effort To create Grid workflows where components can also be legacy code applications To make these functions available from a Grid Portal GEMLCA GEMLCA & P-GRADE Portal Integration

33
UK e-Infrastructure 33 Enhancing useability -2 Some VOs have distinct user and application- developer communities – e.g. bioinformatics, medical imaging Need is for use of Grids without individual certificates – hard to manage for non-specialist and can make the Grid itself vulnerable BRIDGES and GOSC worked out a solution in which the VO logs who did what when, but users can simply access a portal.

UK e-Infrastructure 51 VRE development for Integrative Biology “Whereas the existing IB Grid services have focussed on supporting the core IB experimental workflow - moving, processing and visualising data on the Grid - the IBVRE will support the research process in its widest sense i.e. activities such as identifying research areas and funding sources, building and managing projects/consortia, real- time communication, disseminating results, and provision of training to new researchers entering the field (learning and teaching support tools)”.
